This paper studies the effect of social activities on cognitive functioning of Korean older adults. Social activities and cognitive functioning can have reciprocal relationship, and to address the reverse causality we analyze 2006 to 2018 waves of Korean Longitudinal Panel Study (KLoSA) using Arellano-Bond (AB) GMM estimation. Social activities are classified as formal and informal. Formal social activities are measured as the frequency of participating in religious, leisure, cultural, political activities, sports, alumni societies, and volunteering. Informal social activities are measured as the frequency of engaging in face to face meeting with friends and children. Results from the fixed effects estimation show that for both men and women, social activities have positive relationships with cognitive functioning. However, in AB estimation, for women, while formal social activities are not significantly related with cognitive functioning, meeting friends and children are positively related with cognitive functioning. For men, formal activities are positively related with cognitive functioning even after addressing the reverse causality. By specific skills of cognitive function, informal social activities are positively related with orientation, immediate recall, delayed recall, and language ability for women. For men, meeting with children is positively related with immediate recall. Our results show that the effect of social activities on cognitive function are different for men and women which implies different intervention is required for men and women. In addition, to prevent cognitive decline, participation in formal social activities as well as informal social activities are necessary.
